To prepare the complete medium for this organoid model, please refer to the Organoid Media Formulation #8.

ATCC offers the recombinant proteins, small molecules, and other supplements to make this complete medium; Organoid Growth Kit 1F (ATCC ACS-7105) provides these supplements in a convenient, pre-portioned, ready-to-reconstitute format that does not require aliquoting or storage once prepared.

Seeding density: We recommend seeding this model at 0.25 - 1 x 10⁶/ viable cells in 100 µL of ECM per well of a 6-well plate.

ECM: We recommend culturing this model in ATCC Cell Basement Membrane (ATCC ACS-3035) or Corning Matrigel. Include 10 µM ROCK Inhibitor Y-27632 (ATCC ACS-3030) in medium for the first 2-3 days following subculture.

For a brief overview of the thawing procedure see our quickstart guide Thawing Cryopreserved Human Organoids.

Initiating culture from frozen vials: For a brief overview of the thawing procedure see our quickstart guide Thawing Cryopreserved Human Organoids.

Seeding density: 0.3 - 0.5 x 10⁶/ viable cells in 100 µL of ECM per well of a 6-well plate. Alternatively, split at 1:2-1:4 every 7-10 days. For example, collect organoids from 100 µL of extracellular matrix (ECM) from a single well of a 6-well plate and re-seed into 2-4 wells of a 6-well plate in 100 µL ECM per well.

Note: Mammary cancer organoids may be extremely slow to proliferate. Passing interval may be 3-4 weeks or longer. Keep model at a high density as organoid formation efficiency may decrease or cease if density becomes too low. Mammary cancer models are also very sensitive to mis-handling including over-dissociation.

Media renewal: Perform a complete medium change every 2-3 days. Include 10 µM ROCK Inhibitor Y-27632 (ATCC ACS-3030) in medium for the first 2-3 days following subculture.

For a brief overview of the subculture and expansion of organoids see our quickstart guide Subculture and Expansion of Human Organoids Protocol.

We recommend cryopreserving this model in ATCC Stem Cell Freezing Media (ATCC ACS-3020).

For a brief overview of the cryopreservation procedure for organoids see our quickstart guide Organoid Cryopreservation Protocol.

For more details on the handling and culture of organoids see our methods paper in Current Protocols in Cell Biology.
